The present invention relates to a method and apparatus for cooling intake air prior to entry into a combustion chamber of a boosted internal combustion engine. The invention provides an air intake system comprising a cooler disposed in an intake passage downstream of a charger; a bypass passage for communication between a portion of said intake passage located upstream of said cooler and a portion of said intake passage located downstream of said cooler so as to allow a flow of air discharged from the charger to bypass the cooler; a bypass control valve...
What is claimed is: 1. A method of cooling charge air using a cooler having a cooling passage and a bypass passage comprising the steps of; operating a bypass control valve such that the cooling passage is bypassed under particular engine operating conditions; and in which in the event of failure of the bypass control valve, limiting flow through the bypass passage at a predetermined critical flow rate. 2. A method of cooling charge air cooler according to claim 1 further comprising the step of operating a bypass control valve in response to the temp...
